' COOKING APPARATUS.

Specification of Letters Patent.

Patented April 23, `190'?.

l Application led September 30, 1905. Serial No. 280,812.

Toallwhom it may concern: g

,'Be it known that I, WILLIAM F. MILLS,

a citizen of the United States, residing at "South Bend, in the county of St. Joseph and State of Indiana,- have invented new and "useful Improvements in Cooking Apparatus, l of which the following is a specification.

This invention relates to that class of cookers in which the food is cooked by retention 'Io of the heat therein; and the same primarily -consists of a sectional knockdown receptacle, of a heat-non-conducting material, in lwhich a'cooking vessel containing partly cooked or. heated food is placed and sealed.

115 The invention further consists in providing means for locking theA sections or parts to- "gether so as to effect a erfect seal between the joints thereof and allg placement and at the same time permitting z o` the parts to be dismembered and easily and thorou hly cleaned.

Furt er, the invention consists 1n means whereby the coverof the cooking vesselor Jar will be hermetically sealed when the parts 215'01' the cooker are assembled, thus preventing the escape of steamand heat.

In the drawings accompanying this speci iication, Figure 1 is a perspective view of the cooker complete. Fig. 2 is a central vertical 3o section thereof, and Fig; 3 is an inverted plan view of the 'upper member of the cooker.

In carrying out the invention I construct the parts of the cooker of any suitable material that is a bad conductor of heat, such as Wood or a composition of com ressed sawdust, preferably the latter, as have found that it may be compounded so as to be' practically non-absorbent, which is a desidera tum 1n preserving the sanitary condition of 4o the. cooker.

The cooker includes three members or parts, the` top and bottom members being in the form of disks, (designated 1 and 3.) The bottom m'ember 3 has transverse openings 4 and 5 arranged at diametrically opposite points antlliprovide'd with countersunk portions V6 anjd, the purposes of which will appear hereinafter. similar openings 8 and 9 and also ears 10 1() fr engagement with a. bail 11, so that the cooker may be readily carried' from place to place. -T he intermediate member 2 1s 1n the o prevent their disp bers are inter osed suitable Tlilackings 17,

The upper member 1 has form of a hollow cylinder open at the top and bottom and provided with longitudinal diametrically-arranged opening 1212, adapted when the parts are assembled to yaline with the openings in the top and liottom members, so as to providetwo straight continuous vertical channels through the cooker.

14 designates tie-rods each4 of which is provided with a head 15 on one end and a thread on its other end. These tie-rods are let into the openings in the top, bottom, ,and intermediate members with their heads in the countersinks of the bottom members, and when a thumb-nut 16 is screwed on the threaded ends the members are bound tightly together and also held againstl laterall movement.

Between the contiguous faces' of the mempreferably rub er gaskets. segaskets are com ressed `when the nuts ,16 are screwed own, and a .tight sealis effected between the joints.

yOn the bottom of the top member 1 is a bowed spring 18, the ends of which'are slotted, as at 19, so as to permit it to tyield slightly and slide on its fastenin -pins -20 member is put on and the nuts 16 app led,

forcing the s ring 18 against the pot-cover and sealing goth receptacles. The food in the inner vessel will now continue to cook, inasmuch as the heat is retained therein.

It will be seen that the parts may be easily dismembered and cleaned and shipped and stored in compact form.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

A cooker of the class described embodying top and bottom disk members and an intermediate, hollow member engaging the disks near the edges thereof and forming therewith IOC a cylindrical receptacle, said disks and said hollow member havihg alining vb'penings, tiecooking vessel withinl the -cooker, substanrods disposed in the said openings and having tially as specified.

heads countersunk in the bottom disk, n In testimony whereof I a'ffix my signattue thumb-nuts on the ends of the rods and ennpresenoe of tw o subscribing Witnesses. 5 gaging the top disk, packing between the oon- WILLIAM F. MILLS.,r tiguous faces of the disks and hollow em' Witnesses: ber, and a bowed spring on the bottom of the GEORGE OLTsoH, topdisk adapted to engage the cover of a ETHEL MIKELS.
